由於安裝了稍微太新的軟體包而導致的未滿足的依賴關係

當我嘗試apt-get upgrade（是的，我先進行了更新）時，我得到以下資訊：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python-samba : Depends: libwbclient0 (= 2:4.5.12+dfsg-2+deb9u2) but 2:4.5.12+dfsg-2+deb9u3 is installed
               Depends: samba-libs (= 2:4.5.12+dfsg-2+deb9u2) but 2:4.5.12+dfsg-2+deb9u3 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

所以罪魁禍首似乎libwbclient0是顛覆中需要deb9u2但顯然安裝在deb9u3. 當我嘗試按照刪除腳本--fix-broken的建議執行時，apt-get似乎由於缺少包maketrans而崩潰，後來ConfigParser：

我在使用核心的 debian stretch 9.4： Linux 3.10-2-amd64 #1 SMP Debian 3.10.7-1

在我自己的嘗試失敗並且我無法在網上找到任何解決此問題的方法後，我要求aptitude並synaptic試一試。兩人都嘗試過，但也失敗了。

我什至不需要 samba，所以擺脫它會很好，但apt在我不修復損壞的包之前不想刪除任何東西：

package is in a very bad inconsistent state; you should
reinstall it before attempting a removal

ImportError: cannot import name 'maketrans'

是一個 Python 3 錯誤，它是由於嘗試maketrans像在 Python 2 程式碼中那樣導入而導致的。這意味著/usr/bin/python在您的系統中有一個 Python 3 解釋器；這破壞了 Debian 衍生產品。

要解決這個問題，假設python2.7仍然安裝，您需要修復/usr/bin/python符號連結，使其指向/usr/bin/python2.7：

sudo ln -s python2.7 /usr/bin/python
